'e The transferring apparatus operates as fol- 105 For this purpose the grip 3 comprises two relalows:` When the grip 3, consequent upon the rotively movable jaws 5 and 6, which can be opertation ofthe armr9, reaches the blowing machine Y ated, so as to seize the bottle 1 under the 'collar in front of the mold, the compressed air acting on L of the neck 7 and to release it at the opportune the' piston 15 causes the pusher 18 to move to- 'moment over a receiver 4 mounted Aon avtable wards the shaft 10. The pusher rst moves the .1 12 earned by a rotatable smit 1a. v'inebome nose piece 2a laterally, which causes tnegnp 3 a l 0 open against the action of the spring 25. It then causes the carriage 17 itself to move towards the shaft 10, thereby bringing the jams 5 and 6 of the opened grip 3 to either side of the neck 7 of the bottle. The air pressure admitted at this moment on the face 24 of the piston 15, causes the pusher 16 to start its return movement in the direction of the arrow. As soon as, the pusher 16 has passed the nose piece 23 the spring 25 closes the grip 3, which has just been opened, around the neck of the bottle resting on the bottom 2 of the mold, and the pusher 16 acts again on the carriage 17 so as to move the latter towards the free end of the arm 9 in the direction of the arrow, so that the grip 3 which, on closing,l has seized the bottle, withdraws the latter from the blow mold by transferring it across the free space between the open halves of the mold.

After the rotating arm 9 has conveyed the bottle over the rotating table 12, the pusher 16 returns some way towards the shaft 10, so that grip 3 opens again; and releases the bottle which is thus placed on the base piece 11 mounted on the rotary table 12 which then begins to rotate.

In order to prevent the arm 9 from being hooked by the bottle resting on the` rotating table 12, according to the present invention the arm 9 is lifted after the grip 3 has been opened so as to become placed over the plan of rotation of the arm 9.

This lifting of the arm 9 may be obtained by any suitable means, such as a mechanism operated' by compressed air.

When the bottle has been moved by the table 12 from under the arm 9 the latter is lowered again and the pusher 16 is moved back by the piston 15 towards the free end of the arm 9. This allows the grip 3 to be closed, whilst the carriage 17 remains in its extreme position towards the free end of the arm 9. The arm 9 then returns towards the mold, and when it is situated in front of the latter, the piston 1.5 is again operated by compressed air, and the cycle of operations begins anew.

The bottle released by the grip .3 is held in place on the table 12 by means of two movable curved plates 26 and 26', which, when brought together, form the receiver 4. The receiver is adapted to open before it is brought under the grip 3, by the table 12, so that a bottle can be placed in the receiver even if its base is of larger section than the rest of it.

For this purpose, each plate of the receiver is hinged to a carrier 27 operated in the following manner: a blowing machine admits compressed air into the cylinder 28, the piston of which tilts a lever 29 hinged to a fixed supporting table '30. In tilting the top end ,of this lever 29 engages the rack 31, fitted on the lower side of the table 12 and meshing with two pinions 32, the shafts of which support the` carriers 27. The displacement of the rack 31 by the lever 29 thus causes the receiver 4 to open.

During the rotation of the table 12, when the rack 31 passes in front of a cam 33 secured to the supporting table 30, it is moved back towards the periphery of the table 12 so as to open the receiver 4 and the bottle, which vis now sumciently cooled, is tipped out by the base piece 11 in a known manner.

For the sakc of clearness the rack 31 and the pinions 32, which are in practice mounted on the lower face ofthe table 12, are shown in Fig. 1 a certain distance away from this table.

In order to coordinate the movements of the table 12 with those of the arm 9 their movements are controlled by the blowing machine, for instance, by means of compressed air acting on pistons not shown in the drawing, such pistons being connected to the racks 34 and 35 which actuate respectively the pinions 36 and 37 keyed respectively to the shafts 10 and 13.

Fig. 2 shows another embodiment of the swinging arm 9. In this embodiment the sliding carriage 17 which carries the grip 3 is shown in the position which it occupies, before the grip, already brought into position between the halves of the opened mold, have seized the bottle.

In this embodiment the pusher 16 of a tapered form cooperates with the rod 20 in order to open the jaws 5 and 6. The carriage 17 isl constructed so as to slide on a central guide bar 38 rigidly secured to the rotating shaft 10.

From the above description it will clearly be seen that the transferring apparatus according to the invention, in which the swinging movement of the arm is combined with the extraction of the bottle from the mold by a rectilinear displacement of the bottle overcomes the risk of damage to the-bottle on its removal from the mold, whilst limiting to the strictest minimum the opening of the halves of the mold.

Furthermore, it allows bottles of any size or form, be they of taper or irregular shape, to be mechanically transferred from the mold of the automatic blowing machine to the point where they leave the receiver of the rotating table in a sufllciently coiled condition.
